MURS Dakota Alert IR Sensors and Antennas – Part 1, by Tunnel Rabbit
The case for using directional antennas to contain signals within an area of operations (AO), has hopefully been adequately made in my previous SurvivalBlog articles. Today, I will describe how directional and omnidirectional antennas can be used with MURS Dakota Alert Sensors. With the advent of HF equipment that can now be operated on very low power, there has been a growth in interest among some Amateur radio operators in QRP (low power). It is a style of HF (High Frequency, a.k.a. shortwave) radio that challenges operators to communicate very long distances using only very low powered transmitters. This style …
